I think a titular change would actually be a disservice to the plot, because the way it's written, it immediately draws the audience into questioning the word. I feel as though it was titled, specifically, with the "!?" to draw the audience's attention and actually get them to think about how the word is being used. For instance, even in the original release, the first time Brayden uses the word, it's more implied to mean "chill with it", as in his roommate's sexuality, but the reality is that, from that moment, the audience was tricked into thinking we're watching a straight guy question his sexuality, while in reality, we're witnessing a questioning guy on his way to come to terms with his sexuality. Both Brayden and Zach are in very similar situations, with neither of them really understanding that, and being so wrapped up in their own problems that they didn't realizw the person they cared about most was going through a similar issue. That's how I perceived the story and how it relates to the tile, at least.
heya, thanks for chiming in on this. that's actually my head canon in writing it as well. Obviously, people are allowed their own interpretation and whichever one makes you the happiest with the story is the one you should go with. Also, i chuckled in reading your post because you explained it way better than i did and I wrote the damn thing, lmao.
So thanks for the assist :p
